Question

A patient with atopic dermatitis has been using a high-potency topical corticosteroid ointment for several weeks. Which finding by the nurse indicates a possible adverse effect of the medication?

a.Thinning of the affected skin
b.Alopecia of the affected areas
c.Reddish-brown discoloration of the skin
d.Dryness and scaling in the areas of treatment

Answer 1

Skin thinning is the adverse effect linked to prolonged use of high-potency topical corticosteroids, which can reduce inflammation but may cause atrophy with overuse.

Step-by-step explanation:

Thinning of the affected skin is the adverse effect indicating the overuse of high-potency topical corticosteroid ointment for atopic dermatitis. Topical corticosteroids such as hydrocortisone are effective treatments for reducing inflammation and relieving symptoms like itching and rashes by suppressing histamine production and the immune response. However, prolonged use, especially of high-potency formulations, can lead to skin thinning or atrophy. This makes the skin more fragile and susceptible to bruises and tears.

Adverse effects such as alopecia (hair loss), reddish-brown skin discoloration, or dryness and scaling, while possible, are less commonly linked to corticosteroid use. Eczema, as a condition, typically involves dry and itchy patches of skin. Corticosteroids treat the symptoms of inflammation but do not address the underlying cause. In the case of an allergic reaction, avoidance of the allergen—in Penny's example, the new sunscreen—along with symptomatic treatment, is essential for resolution.
